CARlDlNG-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 597,314, dated January 11, 1898.

Application filed August 30, 1897 Serial No. 649,911. (No model.)

To @ZZ whom t may concern:

Be it known that I, MELVIN HQCOEFIN, of Whitinsville, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Carding Machines; and I herebydeclare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this speci- Io iication.

This invention has reference to an improvement in revolving-flat carding-machines; and it consists in the peculiar and novel construction of a clearer, whereby the positions of the r 5 flats with reference to the carding-cylinder are maintained, as will be more fully set forth hereinafter.

In revolving-fiat carding-engines the flats, which are connected by chain-links to form zo an endless series of connected flats, are supported on disks secured to two shafts, one of which is rotated, so that the chain of iiats is continually moving off from the carding-eylinder around one pair of disks and onto the carding-cylinderV around the other pair of disks. Floating fiber and dust collect on the peripheral surface of the disks and if a1- low-ed to accumulate disturb the adjustment of the iiats with reference to the carding-cyl- 3o inder, and more particularly of the clean flats when they are rst presented to the main carding-cylinder. The object of this invention is to automatically clean the peripheral edge of these disks, and particularly the disks supporting the delivery end of the chain of dats.

Figure l is a side View of part of a revolving-fiat (raiding-machine, showing my invention. Fig. 2 is a top View of part of a re- 4o volVing-flat carding-engine, showing the clearer in connection with one of the disks.

Similar letters of reference indicate corresponding parts in both figures.

In the drawings, A indicates the shaft of the main carding-cylinder; A', a pulley secured to the shaftv A; B, the side frame or casing of the carding-machine; C, the rear disk; C', the front disk on which the ends of the flats D D are supported. The revolv- 5o ing flats are driven from the pulley A by a belt passing around the pulley A2, by which through suitable gears the worin A3 is rotated, which engages with the worm-wheel A4, secured to the shaft A5, near the opposite ends of which the disks C are secured. Asprocket- 5 5 wheelA6 (shown in broken lines in Fig. l) rotates with the shaft A5, and, engaging with the chain connecting the flats D D, imparts motion to the revolving iiats. The brushroller E extends across the width of the chain 6o of revolving flats. It is journaled in brackets E', secured to the opposite sides of the casing B of the carding-machine and, is provided with the ratchet-wheel E2. To secure the thorough cleaning of the backs of the ats,the brush-cylinder has to be rotated, and to secure this rotation the shaft F is supported in the brackets F', secured to the opposite sides of the casing B of the cardingengine. To the shaft F, at opposite ends, is 7o secured the arm F2, on which the rider F3 is adjustably secured, usually by means of a set-screw. On the lower end of the rider F3 is journaled a small wheel F4, which rests on the cam F5, connected with the pulley A2, so as to rotate with thesame. An arm FG is secured near each end to the shaft F, and to the upper end of this arm is pivotally sccured the pawl F7, which engages with the ratchet-Wheel E2 on the brush-cylinder. To 8o the arm F6 is also pivotally secured the clearer F8, which rests on the peripheral surface of the disk O and extends down on the side of the disk. The forward edges of the clearer F8 are finished to a scraping edge adapted to 85 remove lint, dust, or other impurities liable to settle on the disks. As the disks G' controi the presenting of the cleaned 'Hats to the main carding-cylinder and as the collection of lint and dust on the disks disturbs the ac- 9o curate adjustment required to secure the best work, these clearers are more particularly required on these disks C', but they maybe also used in connection with the disks C by extending the end of the pawl F' and pivot- 95 ally connecting therewith the counterweighted clearer f8. (Shown in broken lines in Fig. l.)

When in use, the small wheel or roller F4 of the rider is raised and lowered at each roo revolution of the pulley A2 and caln F5, imparting an up-anddown motion to the arm F2, and as this arm F2 forms with the arm F6 f a bell-crank lever the motion is transmitted to the arm Il G'and by it to the pawl F7 and clearer F8, aswell as to the clearer f8, if the same is used. The oscillating motion of the arm Fi gives to the clearer F8 a positive scraping action by which the dirt, lint, and' im'- pnrities are removed from the peripheral sur`- face of the disk C' on one side, and a similar arm F6 operates a similar clearer FS on the opposite side of the cardingmiachine.

Having thus described my invention, xI claim as new and desire to secure by Letters Patent- 1. In a revolving-fiat carding-machine, the combination With the disks supporting the ia'ts, and the flats, of an oscillating member, means, substantially as described, for oscilf lating the member, and a clearer pivotally supported on the oscillating member and held against the peripheral surface of the disk.

2. In a revolving-dat card, the combination with the flats, the disk C', the cam F5, the rider F3, the arms F2 and FG, the pawl F7, and the brush roll provided with the ratchetwheel E2, of the clearer FS pivotally con* y
